Spire is Baseball Boss' premium brand of cards. They degrade in game play nearly two times as slowly as National cards. All Spire cards have a 20% salary reduction compared to their National counterparts. Plus, Spire is the only brand that includes rare Tier 6 and Tier 7 cards.
National is Baseball Boss' value-priced brand. While they degrade faster than Spire cards and don't benefit from salary reductions, they are a good choice for an owner looking to build a dynasty on a small market budget
